KVM: arm64: Factor out TG0/1 decoding of VTCR and TCR

Browse source

The current code decodes TCR.TG0/TG1 and VTCR.TG0 inline at several
places. Extract this logic into helpers so the granule size can be
derived in one place. This enables us to alter the effective granule
size in the same place, which we will do in a later patch.
